VALVE.

SPECIFICATION forming part of Letters Patent No. 495,739, dated. April18, 1893.

Application filed May 11, 1892.

To aZZ whom it may concern.-

Be it known thatI, DANIEL KENNEDY, a citizen of the United States,residing in the city and county of New York, State of New York, haveinvented a certain new and useful Improvement in Valves, of which thefollowing is a specification.

My improved valve is intended for controlling water, steam or otherfluids for domestic manufacturing and other purposes. Itis Well adaptedfor controlling the supply of steam for hoisting engines and analogousengines whlch require to be instantly stopped when their work isaccomplished.

My improved valve gives a straight passage for the water, making it whatis sometimes termed a straight-way valve. It also allows of being openedrapidly to its full extent, and of being closed instantly and tightly.

The accompanying drawings form a part of this specification andrepresent what I consider the best means of carrying out the invention.

Figure 1 is a side elevation. Fig. 2 is an end view. Fig. 3 is a sectionon the line 3 3 in Fig. 1. Fig. 4 is a section on the line 4 4 in Fig.2. Fig. 5 is a vertical section on the 1 line 5 5 in Fig. 2. Figs. 6, 7and 8 are views of the disk detached. Fig. 6 is a face View. Fig. 7 isan edge View. Fig. Sis an edge view at right angles to the view in Fig.7, and Fig. 9 is an elevation showing a modification.

Similar letters of reference indicate corresponding parts in all thefigures where they appear.

A, is the body or casing of cast brass or other suitable material,certain portions being designated when necessary by supernumerals as A.

B, is a disk having both faces plain but set oblique to each other sothat the disk will apply wedge-wise between the two finished faces ofthe casing which serve as seats. A rib A, in the interior of the casingserves as a guide, the disk being formed with a groove 5', adapted tomatch on the rib A, to guide the disk thereby as it is rapidly movedinto the desired open and closed conditions.

D, is a shaft mounted in bearings in the casing and having asquaredportion D, which is fitted in a corresponding square hole in a hub E,which carries an arm E, which latter Serial No. 432,551- (No model.)

engages in a deep recess b,in the disk. Rocking the shaft D, by means tobe presently described acts through the arm E, to carry the disk firstinto wedging contact between its seats A*, A*, in which position thevalve is tightly closed, and next into the liberal space provided in theupper portion of the chamber, being partially in the cover A leaving apassage for the Water through the valve and through the connectingpipe-lengths G, 0 which is entirely open to the full capacity of thepipes.

The shaft D is extended out at each end secured by a stuffing box. Eachend beyond or outside of the stuffingbox is squared and receives a leverG. The outer ends of the two levers G, arerigidly connected by atransverse handle H fitted with a covering of wood or othernon-conductor of heat, so that the valve may be used for steam bygrasping the handle H, and turning the shaft.

I, is a shield rigidly connected by the arms I, and screws 1 to theinner faces of the levers G. WVhen the handle H, is raised in itshighest position as shown, the valve is closed and the shield I standsin a position which exposes the word Shut, which is cast or otherwiseprovided on the exterior of the casing. To open the valve, the handle ispulled in the direction indicated by the arrow in Figs. 2 and 3. Thismovement raises the disk B into the upper portion of the chamber in thecasing A. The same movement depresses the shield I, so that it coversand conceals the word Shut and exposes another word Open.

A A are fiat plates of cast brass or other suitable material heldstationary in the structure bybeing clamped by the gland of the stuffingbox (see Fig. t). The exterior of each plate A carries the words 0 penand Shut (see Fig. 2).

J, is a thumb-nut fitted on a bolt K,carried on one of the arms E, andtraversing in a curved slot a, in the adjacent plate A WVhen the valveis to be held fast in the open or closed position or-in any intermediateposition, the nut J, being turned on its bolt K, in

the direction to tighten, seizes the metal of the plate adjacent to thecurved slot C6, and holds the parts rigidly until the nut shall again berelaxed.

Each lever G, G,is widened at a point alittle nearer the center than thescrew bolt K, thus forming additional shields, which as the valve isopened and shut, alternately covers and exposes further words Open andShut which are produced in raised letters or otherwise on the outerfaces of the plates A The wedged form of the disk and the correspondingpositions of the seats A A insure that the valve B moves with littlefriction except when it is in the act of completing its closing orcommencing its opening motion. The levers G, G, receiving force from thetransverse handle H imparts the necessary partial rotation to therocking shaft D, and the fact that there are two of these leversconnected by a handle with a non-conducting surface avoids the usualtwisting strains on the shaft and on the bearings therefor, and alsoavoids the exposure of the hand to excessive heat when the valve is usedfor steam. The rib A nicely finished by tools or by the smoothness whichcan be produced by casting, being received in the groove b in the disk,guides it reliably. The steam or other fluid may tend to move in eitherdirection. The faces of the disks are in tight contact with'each seat.

Modifications may be made in the forms and proportions, withoutdeparting from the principle or sacrificing the advantages of theinvention.

Parts of the invention may be used without the. whole.

Fig. 9 represents a construction in which one of the levers G, and thehandle H, is omitted, and the clamp for holding the valve firmly in anydesired condition is modified in form and arrangement. I prefer theconstruction shown in the preceding figures.

I claim as my invention 1. A straightway valve, having a casing A, withinclined seats A*, A*, and an internal rib or guide A, in combinationwith the disk B, having agroove b and faces inclined to correspond tothe said seats, and the rocking shaft D and arm E engaged with saiddisk, all arranged for joint=operation substantially as hereinspecified.

2. A straightway valve having a casing A, with inclined seats A*, A*, aninternal rib or guide A, and the words Open, Shut or the equivalentmeans of indicating on the exterior the condition of the valve, incombination with the shield I carried on the operating mechanism andarranged to cover and uneearse cover the words, and with the disk B,having a groove 1) and faces inclined to correspond to the said seats,and the rocking shaft D, and arm E, engaged with said disk, all arrangedfor joint operation substantially as herein specified.

3. A straightway valve, havinga casing A, with inclined seats A*, A*,and an internal rib or guide A, in combination with the disk B, having agroove 1), and faces inclined to correspond to the said seats, and therocking shaft D and arm E engaged with said disk, the two levers G, G,one on each end of said shaft, and the handle H connecting such levers,all arranged for joint operation as herein specified.

4. A straightway valve having a casing A, with inclined seats A*, A*, aninternal rib or guide A, and the words Open, Shut or equivalent means ofindicating on the exterior the condition of the valve in combinationwith the disk B, having a groove 1), and faces inclined to correspond tothe said seats, and the rocking shaft D, and arm E, engaged with theshield I carried on the operating mechanism and arranged to cover anduncover the words, and with said disk, the two levers G, G, one on eachend of said shaft and the handle H, connecting such levers, all arrangedfor joint operation as herein specified.

5. A straightway valve having a casing A, with inclined seats A*, A*,and the words Open, Shut or equivalent means of indicating on theexterior the condition of the valve, in. combination with the disk B,having a deep recess b, in one edge and the groove 1), in the oppositeedge, and having faces in? clined to correspond to the said seats havingthe shaft D and arm E engaged with said disk, the two levers G, G, oneon each end of such shaft and a handle H, arranged parallel to the shaftD, and connecting such levers, and shields carried on said shaft D, androcking therewith, adapted to cover and uncover the said indicatingwords or marks as the shaft is rocked, all arranged for joint operationsubstantially as and for the purpose herein specified.

In testimony that I claim the invention above set forth I affix mysignature in presence of two witnesses.

DANIEL KENNEDY.
